IMPROVEMENT IN MEAT-LCUTTERS.

Specification forming part of Letters Patent No. 16L96L, dated April 13,1875 application filed January 9, 1875.

To all whom it may concern:

Be it known that I, JOHN H.H0LL1NGER, of the city of Lancaster, in thecounty of Lancaster and State of Pennsylvania, have invented certainImprovements in Machines for Mincing or Cutting Meat, of which thefollowing is a specification, reference being had to the accompanyingdrawings making a part of the same, which, with the letters of referenceand a brief description, will enable those skilled in the art to makeand use the machine, ot'which- Figure lis a perspective view, showingone side and one end with gear; Fig. 2, a vertical side View, to showthe two series of knives and blocks, 8vo.; Fig. 3, an end view of thesame, with the follower M removed. Fig. 4 shows the knives and blocksremoved, to show the central shaft. Fig. 5 shows a top view of theshaft, knives, blocks, followers, Snc., Fig. 6, a perspective view of asingle block, knife, and double guides or pins.

The object of this invention is to obviate the casting of curvedsections or cylinders to surround a central revolving shaft in machinesfor mincing meat, as well as to obtain a rightangled chamber on lrwoopposite sides of the central shaft, for. the reception of a series ofri ght-an gled wooden blocks, having their inner vertical face centrallymade concave, and alternating with right-angled knives, all separatelyset in against or between simple shoulders or iianges cast on the innerface of the two prolonged parallel side pieces of the case, so arrangedthat the combined vertical pile in each chamber is compressed and heldby a single set-screw entering through the top, and the knives adjustedand held horizontally by a single follower, that also closes the ends.

Fig. l shows the one side, A', with a hopper, H, the bearings b securedto the top by the bolts and nuts G, shaft and bevel-pinion B,crank-handle o, set-screws D. The end shows the follower M and knob m,which sets in between the sides and under the top. A metalliccross-strip is shown above at N, and the side notched holders K, toreceive a cross-bar, L', which has a central screw-thread for abinding-screw, l, to press the follower above and below against thebacks of the series of knives. (These catches K and clamps L are shownsimplified from those marked K L on the other end of Fig. l.) W is abase-board, to which the sides are bolted at J. This board extends oneach side, and has a slot, w, by which it can be secured over a tub orvessel to receive the eut meat through an opening, U, Fig. 4, which alsoshows an adjusting-slide, X V, to regulate the discharge to the properaction of the knives. Fig. 2 shows the two series of knives P and blocksO. On each side ofthe central column or shaft F the knives extend backbehind the blocks, to allow of being sharpened and pressed up by thefollower M. As they wear od' in time, the blocks O, set between two sideiianges, dQ, and the inner verticalface, are made concave, to allowspace for the slotted or double pins I on the shaft to pass. These pinsI are arranged somewhat spirally, but on the horizontal plane of theknives, which, as shown, are arranged so as to allow the projectingblades P to pass through the slot or intervening space as the shaft isrevolved. Fig. 6 shows one block, O, and knife, P, under it, with adouble pin, I, or guide and cleaner, or holder, to facilitate thecutting operation, which may be summed upin a few words.

The meat to be minced is best cut in long strips and placed into thehopper. The spiral flange f catches it, draws it in, and presses itdownward, when it is subjected to the action of the knives, as it isregularly carried round and gradually spirally downward across theledges of all the knives, until it reaches the bottom of the shaft,where it is hollowed out, and where it is discharged lthrough anopening, U, aforesaid. In order not to allow the discharge to be toofast, a slide, V, with a slot and headed pin, x, is employed forregulating it. A screw, T, in the step is shown to regulate the shaft.The top of the case can be taken off. The blocks arereadily slippedoutby relaxing the binding-screw D on top. There is an open space betweenthe lug and flange d d', through which the blocks can be slid out, andthe knives can thus be removed for being ground or sharpened, or forcleaning. They simply t between the flanges, and are heldin place by theblocks, tightened down by the set-screw D on each side. The upper block,marked XII, is faced with an iron plate to resist t-he action of theset-screw D. The succeedingbloeks downward toI are vmade gradually lessin thickness, to bring the 'knives in closer proximity as the meat isbeing cut finer. The object of forming right-angled chambers in the twoends is to allow the use of rightangled blocks, more especiallyright-angled knives, so easily made, ground, and put in and held inplace.

I am aware that in Patent No. 50,984, of November 14, 1865, a verticalscrew-shaft is combined with knives around it, and a screwformed feeder7having also a knife on its top to cnt the meat, and the interior of thecurved segments or cylindrical case provided with projections; andPatent No. 61,424, January 22, 1867, in which the knives are insertedthrough slots in the cylindrical case, and a gang or series of knivessecured by project ing ribs and clamped by an end screw. There are alsopartial chambers shown in Patent No. 110,721, January 3, 1871, forcurved knives, to adapt them to the curved sections hinged together, toform the case or cylinder. But I disclaim the use of cylinders orsectional cylinders surrounding the shaft to form the external shell, bethe knives and blocks arranged as they may. I am aware, also, thatdouble spikes are not new 5 nor do I claim such apart from thecombination and arrangement herein specified.

What I claim in a meat-mincing machine having a central shaft operatedby bevel-gear in the ordinary manner, is-

The combination of a vertical series of alternating, graduated,right-angled blocks, 0, and

yknives l?, when set against and between flanges
